Abstract
Conclusions
The lymphatic system of the dog's hind extremity does not play a significant role in the mobilization of intramuscularly injected sodium, nor does the radioactive material diffuse along intramuscular planes beyond the range of the Geiger-Mueller counter.
Intramuscularly injected radioactive sodium can be quantitatively recovered from femoral vein blood if the collateral venous system of the upper thigh is occluded.
The rate of removal of sodium 24 measured external to the site of injection is the same as that determined from the blood actually draining from the muscle.
